Working process of a DENO Waterjet?

The working process of a DENO Waterjet cutting machine involves several key steps, from the initial setup to the actual cutting operation. Here’s a detailed overview of how the DENO Waterjet works:

1. Preparation

- Material Placement: Place the material to be cut on the waterjet cutting table. Ensure it is properly secured and aligned according to the cutting plan.

- Setup Software: Load the design or cutting file into the waterjet’s control software. The software generates the cutting path based on the design specifications.

2. Machine Setup

- Nozzle and Abrasive: Install the appropriate cutting nozzle and, if needed, set up the abrasive delivery system. Choose the nozzle size and abrasive type based on the material and cutting requirements.

- Pressure Settings: Adjust the water pressure according to the material thickness and type. Higher pressure allows for cutting thicker materials and achieving finer details.

3. Cutting Process

- Waterjet Generation: The process starts with a high-pressure pump that pressurizes water up to 60,000 psi (or higher, depending on the machine). The water is then forced through a small nozzle, creating a high-velocity jet of water.

- Abrasive Mixing: For cutting hard materials, abrasives (like garnet) are mixed with the waterjet stream. This abrasive mixture increases the cutting capability of the waterjet.

- Cutting Path: The high-pressure waterjet, or the abrasive waterjet if applicable, follows the path defined by the software. The machine’s motion system (usually with X and Y axes) moves the cutting head precisely along this path to cut the material.

- Material Removal: As the waterjet cuts through the material, the waste material is washed away by the jet stream, and the cut part is left behind. The cutting table often includes a water tank to catch and filter the waste material.

4. Post-Cutting

- Inspection: After cutting, inspect the parts for accuracy and quality. Check for any imperfections or deviations from the design specifications.

- Cleaning: Remove any residual abrasive or material debris from the cutting area and the machine. Clean the cutting table and ensure that the work area is free of waste.

- Maintenance: Perform regular maintenance checks on the machine, including checking the nozzles, water filters, and high-pressure pump, to ensure optimal performance.

5. Operator Training and Safety

- Training: Ensure that operators are trained in machine operation, safety procedures, and maintenance. Proper training helps in achieving accurate cuts and minimizing risks.

- Safety: Follow all safety protocols to prevent accidents. This includes wearing appropriate personal protective equipment (PPE), ensuring proper ventilation, and following machine safety guidelines.

Summary

1. Prepare the material and setup the machine.

2. Adjust nozzle, abrasive, and pressure settings.

3. Start the cutting process with the high-pressure waterjet.

4. Inspect and clean the work area post-cutting.

5. Follow training and safety protocols.

By following these steps, the DENO Waterjet can efficiently cut a variety of materials with high precision and minimal waste.
